Summary:Aggregate base course is one of the most significant and bulky material used in road construction projects. Literature on the Key Performance Indicators (KPIs) that can be used to control the of aggregate base course waste generation during the construction phase of a road project, especially from the contractor's perspective, is scarce. Thus, the aim of this study was to identify the KPIs for managing the aggregate base course waste in road projects from the perspective of a contractor. A quantitative research approach comprising three Delphi rounds was used to collect the empirical data, which were analysed using statistical data analysis tools. The study revealed that the use of the wrong construction method is the most significant waste generation factor, while proper supervision is the most significant strategy to overcome the generation of aggregate base course waste. The experience and qualifications of technical staff related to the handling of aggregate base course waste is the most significant KPI for controlling the aggregate base course waste generation in road constructions. The study contributes to knowledge and the industry by minimising aggregate base course waste while reducing cost and time overruns and enhancing the performance and sustainability of road construction projects.
